Purpose

This webpage/report is intended to aggregate information from different agencies (i.e. USACE, SFWMD, FWC, USGS and NOAA) into one spot to help inform local government agencies and stakeholders on conditions within Lake Okeechobee, the Caloosahatchee River and Estuary and Coastal southwest Florida. The data provided here should be considered preliminary and are subject to change.

USACE Data Summary

Caloosahatchee Conditions Summary: Flow to the Caloosahatchee Estuary had a 7-day average of 2,123 cfs at S-79 with a 7-day average of 1,879 cfs (89%) coming from the lake at S-77. The 14-day moving average flow at S-79 is 2,067 cfs and has been in the optimal flow envelope (750 - 2100 cfs; RECOVER 2020) for 67 days.

Lake Flows: In the past 7 days the total outflow from Lake Okeechobee was 47,120 AF with 26,091 AF to the Caloosahatchee through S-77,444 AF to St Lucie through S-308, 887 AF through S-310 in Clewiston, and 17,699 AF to the EAA through S-351, S-352, and S-354. The total net inflow to the Lake was 13,357 AF (13,357 AF from Fisheating Creek, S-71, S-72, S-84s, S-65EX, and S-65EX1) . Water conservation areas received flows of 1,220 AF, 0 AF, and 4,639 AF at WCA1, WCA2, and WCA3, respectively. Everglades National Park received 11,766 AF.
